NVIDIA Quantum MQM8790-HS2F 200Gb/s InfiniBand Switch
The NVIDIA Quantum QM8790 is a high-performance, fixed-configuration InfiniBand switch designed for next-generation data centers. It delivers 200Gb/s per port, supporting up to 40 non-blocking ports with a total bandwidth of 16Tb/s. Ideal for HPC, AI, cloud, and storage infrastructures, this switch offers exceptional low latency, advanced in-network computing, and flexible deployment options.
MQM8790-HS2F Key Features
- 40 ports of 200Gb/s InfiniBand or 80 ports of 100Gb/s with full bidirectional bandwidth
- NVIDIA SHARP™ technology for in-network computation offload
- Support for MPI, SHMEM, and NCCL communication frameworks
- Hot-swappable, redundant 80 Plus Gold power supplies
- Advanced management via CLI, WebUI, SNMP, and JSON
MQM8790-HS2F Core Technology
The QM8790 leverages NVIDIA’s Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) to perform collective operations within the switch, significantly reducing latency and improving throughput for HPC and AI workloads. It supports adaptive routing, congestion control, and multiple topology configurations including Fat Tree and DragonFly+.
MQM8790-HS2F How It Works
The switch processes data in transit using embedded hardware accelerators. By aggregating and reducing data within the network, it minimizes the need for multiple transmissions between servers. Each port can operate at 200Gb/s or be split into two 100Gb/s ports, offering deployment flexibility and double-density radix.
MQM8790-HS2F Applications
Ideal for:
- High-Performance Computing (HPC) clusters
- Artificial Intelligence and machine learning training
- Hyperscale cloud data centers
- High-speed storage networks
